HENRY S. BARTON, CF OVENSBORC, KENTUCKY.

LIFTING DEVICE.

To all L1/71,0177, it puny concern:

Be it known that I, HENRY S. BARTON, a citizen of the United States, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented a new and useful Lifting Device for Weighing Packages, &c., of which the following is a specification.

My invention relates, broadly, to a device for holding barrels or packages, raising them from the iioor the proper distance, and holding them in such position while they are being weighed.

The invention is especially devised to be used in connection with a United States Government weighing-beam or Government steelyard; but the useis not confined to the particular weighing means, since any kind of steelyard or other weighing device might be used therewith, and although the invention is primarily intended for use in weighing barrels it is understood that any form of package or vessel may be raised and weighed by the means herein describedfthe invention residing particularly in the method of suspension.

Theobject of the invention is to produce a lifting-jack that will raise and support the barrel or package safely while being weighed and at the same time be capable of holding packages or barrels of different lengths and shapes and sizes in any position without the necessity of changing the barrel-hooks or other means of attaching packages to the weighingbeam or steelyard.

Reference is had to the accompanying drawings and the reference-letters marked thereon, in which- Figure 1 isl a perspective view of my importing-plates S S are bent or cast into the shape shown in the drawings, the inside faces of their upper and lower ends being parallel and forming guides in which the quadrant or lifting means Works.

The lower ends of the Specific ion of Letters Patent.

Eatented Aug. 15, 1905.

supporting-plates are bent under the beam T, and the quadrant is provided on one side with a handle H. The quadrant is made of fiat or rectangular iron or steel of suitable size and is suspended between the plates by means of a bolt or pivot-pin B. The upper arm of the quadrant is provided with a series of notches N for the purpose hereinafter described.

The upper ends of the supporting-plates S S are bent over the supporting-beam T, and between said ends is pivoted the catch or locking-pawl C upon the bolt or pivot-pin A. The locking-pawl C is adapted to adjustably cngage any of the notches N for the purpose of holding the barrels, hooks, and weighingbeam in the desired elevated position.

Situated at a proper distance from the bolt B is the supporting-ring R, from which the weighing-beam, hooks, and barrel or packages are suspended.

At the end of the quadrant Q, is hung a weight W, which serves as a counterbalance for the weight of the handle H and tends to keep the handle in a raised position.

In the use of my invention the handle of the quadrant being held in an elevated position by the weight W or by hand the weighing-beam is suspended from the ring R in its lowered position, allowing the barrel-hooks carried at the end of the weighing-beam to be attached to the barrel. The operator then lowers the handle H, which causes the ringR to be raised, thus raising the weighing-beam, hooks, and barrels or packages and allows the barrel to be weighed. Upon lowering the handle H' the catch or pawl C will engage one of the notches N, thereby holding the entire apparatus, with its load, which has been raised, in an elevated position as long as may be desired.

The device will always support the barrel or package in any one of the notches, and it is impossible for the catch to slip and allow the handle to fly up or the barrel to fall. It will also supporta barrel in any position, dependent upon which of the notches the catch is in engagement with, and it obviates raising the barrel to the limit of the hooks. It also allows the use of different lengths of barrels without changing the barrel-hooks, and its safety is assured in any position.

Having thus described my invention, what T claim as new, and desire to secure by Letters Patent, is

l. In a lifting device, the combination of a supporting-beam, supporting-plates secured to said beam, a quadrant pivoted to said plates at the lower side and its upper side passing between the same and weighing means suspended from said quadrant, substantially as described.

Q. In a lifting device, the combination of a support, a quadrant pivoted to said support,

, a pivoted catch for holding` said quadrant and 4. In alifting device, the combination ofthe supporting-frame, the supporting-plates secured thereto, the quadrant pivoted to said plates and having` a handle, a pivoted catch vbetween the simporting-plates and quadrant,

and weighingI mechanism on said quadrant, substantially as described.

In testimony whereof I aflx my signature to this specification in the presence of two subseribing witnesses.
